Entity 1 has the following observed characteristics:
- A lipid- and protein-based outward-facing barrier that encloses a clearly defined and ordered internal environment, chemically distinct from its surroundings.
- The above-mentioned defined internal environment contains an additional compartment enclosed in its own separate lipid-based layer and housing a linear RNA-based genome.
- Detailed molecular analysis of the genome indicates that it has not shared a common ancestor with any extant bacteria within the last 3 billion years.
- Capability to undergo a form of self-directed replication that includes producing accurate copies of its own genome.
Based on the description above, select the best possible classification for Entity 1 from the options below:
- Entity 1 is not a living cell, of any type.
- Entity 1 is definitely a prokaryotic cell.
- Entity 1 is most likely a eukaryotic cell, but more information is needed.
- Entity 1 is definitely a eukaryotic cell.
- Entity 1 is equally likely to be a prokaryotic or eukaryotic cell.
